Overview

As part of PSE’s commitment to providing Kenmore customers with safe, dependable electric service, in 2016 and 2017, we installed a series of distribution reliability projects (listed below).

In 2018, we will continue to strengthen the system by automating two distribution circuits at the Inglemoor Substation. Through automation, these circuits will be operated remotely, eliminating the need for servicemen to patrol the line for damage. This will greatly reduce outage duration for customers.

Circuit KNM-26 has been a low performing circuit for many years. The main issue is much of the distribution line is not on the public right-of-way and very difficult to access for repair. This distribution line was upgraded to tree wire and relocated to the right-of-way along NE 198th St between 68th Ave NE and 62nd Ave NE.

PSE is beginning to install automated distribution switches in certain areas of our service area to test the technology. Installed along Juanita Drive NE and north of NE 145th Street to automatically detect damage and restore power to customers within seconds.

New overhead switches were installed on NE 185th Street to allow crews to restore power to customers more quickly.

A new recloser was installed on NE 195th Street. This work will help prevent some customers from experiencing an outage, test the circuit automatically to quickly restore power, and sectionalize the circuit to red

uce restoration time.

Another new recloser was installed on NE 169th Street, providing the above benefits to the area.

Distribution line was converted to underground line along State Route 522, east of 83rd Ave NE. This joint project with the City of Bothell will improve reliability for Kenmore residents living downstream of our lines along Bothell Way, near Simonds Road.

The Moorlands-Vitulli transmission line upgrade was also completed in 2016. Crews rebuilt 5-miles of transmission line with a higher-capacity 115 kV line between the Moorlands substation in Kenmore and the Vitulli substation in Bothell. This upgrade will provide more reliable electric service to the Kenmore and Bothell areas.
